earring hole

ok so just looking for advice, not really looking for ppl to criticize and start the whole "to pierce or not to pierce" debate. My daughters ears were pierced at 4 months old. She is now 2 years old - same earrings. no problems. they are the type with a ball on the back so it is really hard for them to fall out. but sure enough, somehow one did fall out today. I lost the back, so i tried to put the earring in w a different back bu there was resistance when i pushed the earring in. Is this dried up gunk? infection? it doesnt seem to hurt her, but the earring wont go all the way through the hole!

anyone have similar experience? for now i just cleaned the whole lobe w peroxide and put her to bed. I figure ill try again in the am before taking her to the dr....

Same thing happened except I didn't notice so it was 1-2 days. I could not get it in so we just went ahead and let it go and will be getting it redone at 5 and make a big special memory of it. She has a ton if curly hair so you really couldn't see them anyway. I feel like we got lucky in a way. We got the cute baby with earrings and now we get to have a special memory with our five year old.
